Nipple shield use in the maternity ward increases risk of exclusive breastfeeding interruption in the first six months of infant's life.

OBJECTIVE: The objective of this study was to investigate the association between use of silicone nipple shields in the maternity ward and exclusive breastfeeding interruption in the first 6 months of the infant's life. DESIGN: Cohort study. SETTING: Interviews were conducted personally at the mother's home at 1 and 6 months postpartum and by telephone at 2 and 4 months. PARTICIPANTS: 287 mother-infant dyads. METHODS: Lactating mothers were randomly selected at two maternity wards (one public, one private) in Porto Alegre, Brazil. Data were analyzed using Kaplan-Meier survival curves and Cox multivariate regression. The outcome of interest was exclusive breastfeeding interruption before 6 months of the infant's life. FINDINGS: Nipple shields were used by 6.2 % of the women in the public maternity ward and by 25.8 % of those in the private setting. Median duration of exclusive breastfeeding was 11 days (95 %CI 0.0-36.9) among women who used the accessory vs. 89 days (95 %CI 60.8-117.2) among those who did not. Nipple shield use in the maternity ward was associated with exclusive breastfeeding interruption before 6 months of infant's life (adjusted risk ratio = 1.47; 95 %CI 1.01-2.15). The risk was higher in the first months of breastfeeding, ranging from 2.0 to 1.47 in the first and sixth months, respectively. CONCLUSIONS: The use of silicone nipple shields in the maternity ward increased the risk of exclusive breastfeeding interruption before 6 months of the infant's life, especially in the first months. These findings suggest caution in recommending this accessory to new mothers.

Women's Satisfaction with Breastfeeding and Risk of Exclusive Breastfeeding Interruption.

This prospective cohort study was conducted to evaluate the association between women's satisfaction with breastfeeding at 1 month post-partum and the risk of exclusive breastfeeding (EBF) interruption before 6 months. 287 mother-infant dyads randomly selected from two maternity hospitals were followed from birth to 24 months of infant's age. Women's satisfaction with breastfeeding was assessed using the Maternal Breastfeeding Evaluation Scale (MBFES) at 1 month. The association between women's satisfaction with breastfeeding and risk of EBF interruption before 6 months was estimated using Cox proportional hazards model. Kaplan-Meier survival curves for EBF were compared between women with lower satisfaction with breastfeeding (MBFES score < median 124) and those with higher satisfaction (MBFES score ≥ 124). Median EBF duration in women with higher satisfaction was 120 days (95%CI 109-131), vs. 26 days (95%CI 19-33) in less satisfied women. Each additional point on MBFES promoted a reduction of 2.0% in the risk of EBF interruption. Among women with satisfaction scores < 124, the risk of EBF interruption was 86% higher when compared with those ≥ 124 (adjusted hazard ratio 1.86; 95%CI 1.41-2.46). Lower maternal satisfaction with breastfeeding in the first month post-partum is associated with a higher risk of EBF interruption before 6 months.

Factors associated with breastfeeding abandonment in the first month after the mother's return to work.

The return to work of lactating mothers has been identified as an important risk factor for breastfeeding interruption. We proposed to identify factors associated with breastfeeding abandonment in the first month after return. 252 women working at a hospital who had children aged 12 to 36 months and who were still breastfeeding when returned to work answered a questionnaire containing questions on sociodemographic characteristics, pregnancy, childbirth, breastfeeding and work-related factors. The associations were estimated using adjusted prevalence ratio (aPR), calculated with the hierarchical Poisson multivariable regression model. The following factors showed a significant association with breastfeeding abandonment: using a pacifier (aPR 4.58), cohabiting with someone other than partner (aPR 3.77), having no intention or having doubts about maintaining breastfeeding after returning (aPR 3.39), having a college degree (aPR 2.66), having no support from the infant's caregiver (aPR 2.26), and infant being older when the woman returned to work (PR 1.16 for each additional month of infant age). Longer duration of exclusive breastfeeding was a protective factor (aPR 0.990). Most of the factors associated with discontinuation of breastfeeding in the first month after the mother's return to work are not directly related to the woman's work.

Trends of breastfeeding indicators in Brazil from 1996 to 2019 and the gaps to achieve the WHO/UNICEF 2030 targets.

BACKGROUND: The comprehension of breastfeeding patterns and trends through comparable indicators is essential to plan and implement public health policies. OBJECTIVE: To evaluate the trends of breastfeeding indicators in Brazil from 1996 to 2019 and estimate the gap to achieve the WHO/UNICEF 2030 targets in children under 5 years. METHODS: Microdata from two National Surveys on Demography and Health of Women and Children (PNDS-1996 and PNDS-2006) and the Brazilian National Survey on Child Nutrition-2019 were used. The indicators of early initiation of breastfeeding (EIBF), exclusive breastfeeding of infants 0-5 months of age (EBF<6 mo), continued breastfeeding at 1 year of age (CBF1yr) and CBF at 2 years of age (CBF2yr) were analysed using prevalence and 95% CI. The average annual variation and years to achieve the WHO/UNICEF 2030 targets were calculated for Brazil and the macroregions. Statistical analyses considered the survey's complex sample design for each database. RESULTS: EIBF increased from 36.3% (95% CI 33.6% to 39.0%) in 1996 to 60.9% (95% CI 56.5% to 65.3%) in 2006 (statistically significant) and 62.5% (95% CI 58.3% to 66.6%) in 2019. EBF<6 mo increased from 26.9% (95% CI 21.3% to 31.9%) in 1996 to 39.0% (95% CI 31.0% to 47.1%) in 2006 and 45.8% (95% CI 40.9% to 50.7%) in 2019 (significant increases for 1996-2019 for Brazil, Northeast and Midwest regions). CBF1yr rose from 36.6% (95% CI 30.8% to 42.4%) in 1996 to 48.7% (95% CI 38.3% to 59.0%) in 2006, and 52.1% (95% CI 45.4% to 58.9%) in 2019. CBF2yr increased from 24.7% (95% CI 19.5% to 29.9%) in 1996 to 24.6% (95% CI 15.7% to 33.5%) in 2006 and 35.5% (95% CI 30.4% to 40.6%) in 2019 (significant increase for 1996-2019). The South and Southeast regions need to double the 2019 prevalence to reach the target for the CBF1yr and CBF2yr; the Northeast and North need to increase 60% the current prevalence for the indicator of EBF<6 mo. CONCLUSION: A substantial improvement in breastfeeding indicators occurred in Brazil from 1996 to 2019, although at an insufficient rate to achieve the WHO/UNICEF 2030 targets.

Resumo O retorno da lactante ao trabalho é apontado como importante fator de risco para interrupção da amamentação. Nós nos propusemos a identificar fatores associados ao abandono da amamentação no primeiro mês após o retorno. Compuseram a amostra 252 servidoras de um hospital com filhos entre 12 e 36 meses e que estavam amamentando quando retornaram ao trabalho, fornecendo informações sobre características sociodemográficas, gestação, parto, amamentação e fatores relacionados ao trabalho. As associações foram estimadas pela razão de prevalência ajustada (RPa), obtida usando modelo hierárquico de regressão multivariada de Poisson. Os seguintes fatores mostraram associação significativa com abandono da amamentação: uso de chupeta (RPa 4,58), coabitação com outra pessoa que não o companheiro (RPa 3,77), não ter intenção ou ter dúvidas sobre amamentar após retorno (RPa 3,39), ter curso superior (RPa 2,66), não ter apoio do cuidador da criança (RPa 2,26) e maior idade da criança quando a mãe retornou ao trabalho (RPa 1,16 para cada mês de idade a mais da criança). Maior duração da amamentação exclusiva foi fator de proteção (RPa 0,990). A maioria dos fatores associados à descontinuidade da amamentação no primeiro mês após retorno da lactante ao trabalho não está diretamente relacionada ao seu trabalho.

Skin-to-skin contact after birth: Developing a research and practice guideline.

AIM: Skin-to-skin contact immediately after birth is recognised as an evidence-based best practice and an acknowledged contributor to improved short- and long-term health outcomes including decreased infant mortality. However, the implementation and definition of skin-to-skin contact is inconsistent in both practice and research studies. This project utilised the World Health Organization guideline process to clarify best practice and improve the consistency of application. METHODS: The rigorous guideline development process combines a systematic review with acumen and judgement of experts with a wide range of credentials and experience. RESULTS: The developed guideline received a strong recommendation from the Expert Panel. The result concluded that there was a high level of confidence in the evidence and that the practice is not resource intensive. Research gaps were identified and areas for continued work were delineated. CONCLUSION: The World Health Organization guideline development process reached the conclusion immediate, continuous, uninterrupted skin-to-skin contact should be the standard of care for all mothers and all babies (from 1000 g with experienced staff if assistance is needed), after all modes of birth. Delaying non-essential routine care in favour of uninterrupted skin-to-skin contact after birth has been shown to be safe and allows for the progression of newborns through their instinctive behaviours.

Complementary feeding methods and introduction of ultra-processed foods: A randomized clinical trial.

Introduction: Complementary feeding (CF) is defined as a period when foods, other than milk, are introduced to the infant's diet. Unfortunately, frequent consumption of ultra-processed foods (UPF) has become highly prevalent early in an infant's life. The aim was to verify the association of CF methods with the introduction of UPF in early childhood. Methods: This randomized clinical trial involved pairs of mother-infants, allocated in groups receiving different CF interventions: strict Parent-Led Weaning (PLW); strict Baby-Led Introduction to SolidS (BLISS), or mixed-method. The intervention consisted of a counseling session on healthy eating at the child's 5.5 months of age. A structured questionnaire was created based on the NOVA classification for the definition of UPF and applied at 9 and 12 months. The effect of the CF method intervention was measured by a survival curve for UPF offered for the first time in early childhood between groups. Cox regression was used to estimate its magnitude. The primary analysis was done in three groups (PLW, BLISS, and Mixed) and the secondary analysis was done in two groups (PLW, and BLISS + Mixed). Results: A total of 139 mother-infant pairs were eligible and 129 followed the study. The prevalence of infants who were exposed to UPF in early childhood was 58.9% (n = 76), being 71.4% in the PLW group, 53.3% in the BLISS group, and 52.4% in the Mixed group, without differences between them (p = 0.133). The PLW group intervention had a greater chance of exposure to ice cream or popsicles (p = 0.032) and sweet crackers (p = 0.009), compared with the other two CF groups. The Cox regression did not find significant differences between the three groups. However, the regression with two groups estimated a 38% reduction in the offer of UPF in the BLISS + Mixed group intervention (p = 0.049). Discussion: The CF intervention promoting greater infant autonomy (BLISS and Mixed) was associated with a reduction in the offer of UPF in early childhood. This knowledge may contribute to supporting strategies aimed at reducing UPF consumption by the young infant.

Association between mistreatment of women during childbirth and symptoms suggestive of postpartum depression.

BACKGROUND: Postpartum depression is a common condition in the pregnancy and postpartum cycle. The development of this condition is multifactorial and can be influenced by previous traumas. This study sought to verify whether there is an association between having been exposed to mistreatment during childbirth and presenting symptoms suggestive of postpartum depression. METHODS: This is a cross-sectional study, with the inclusion of 287 women without complications in childbirth, randomly selected from two maternity hospitals of Porto Alegre, southern Brazil, in 2016. Four weeks after delivery, the postpartum women answered a face-to-face interview about socioeconomic aspects, obstetric history, health history, and childbirth experience (practices and interventions applied) and completed the Edinburgh Postnatal Depression Scale (EPDS). From the perception of women regarding the practices performed in the context of childbirth care, a composite variable was created, using item response theory, to measure the level of mistreatment during childbirth. The items that made up this variable were: absence of a companion during delivery, feeling insecure and not welcome, lack of privacy, lack of skin-to-skin contact after delivery, not having understood the information shared with them, and not having felt comfortable to ask questions and make decisions about their care. To define symptoms suggestive of postpartum depression, reflecting on increased probability of this condition, the EPDS score was set at ≥ 8. Poisson Regression with robust variance estimation was used for modeling. RESULTS: Women who experienced mistreatment during childbirth had a higher prevalence of symptoms suggestive of postpartum depression (PR 1.55 95% CI 1.07-2.25), as well as those with a history of mental health problems (PR 1.69 95% CI 1.16-2.47), while higher socioeconomic status (A and B) had an inverse association (PR 0.53 95% CI 0.33-0.83). CONCLUSIONS: Symptoms suggestive of postpartum depression seem to be more prevalent in women who have suffered mistreatment during childbirth, of low socioeconomic status, and with a history of mental health problems. Thus, qualifying care for women during pregnancy, childbirth and postpartum and reducing social inequalities are challenges to be faced in order to eliminate mistreatment during childbirth and reduce the occurrence of postpartum depression.

Development of an instrument to measure mistreatment of women during childbirth through item response theory.

The objective of this study was to structure a proposal for an instrument to measure the mistreatment level of women during childbirth, through item response theory, based on the birth experience of postpartum women. A cross-sectional study was conducted, with the inclusion of 287 women who did not suffer complications during childbirth, randomly selected from two maternity hospitals in the capital of Rio Grande do Sul-Brazil, in 2016. Approximately 30 days after delivery, the women answered questions in a face-to-face interview about their birth experience (practices and interventions applied) and were inquired about their perception of having suffered disrespect, mistreatment or humiliation by health professionals. The set of practices was included in the item response theory model to design the instrument. Of the 36 items included in the model, 21 dealt with practices applied exclusively to women who went into labor, therefore two instruments were developed. The instrument including all women, containing 09 items, identified 23.7% prevalence of mistreatment to women during childbirth, while the instrument for women going into labor included 11 items and identified 22% prevalence. The items with the highest discrimination were: not having had a companion during labor (2.05; and 1.26), not feeling welcome (1.81; and 1.58), and not feeling safe (1.59; and 1.70), for all women and for those who went into labor, respectively. For those who went into labor, the items, did not have a companion during labor (1.22; PE 0.88) and did not feel comfortable asking questions and participating in decisions (1.20; PE 0.43) also showed greater discrimination. In contrast, when directly questioned, only 12.5% of women said they had experienced disrespect or mistreatment, suggesting that harmful practices are often not recognized as violent. Standardizing the measurement of mistreatment of women during childbirth can create more accurate estimates of its prevalence and contribute to the proposal of strategies to eliminate obstetric violence.

Factors associated with breastfeeding continuation for 12 months or more among working mothers in a general hospital. / Fatores associados à continuidade do aleitamento materno por 12 meses ou mais em mulheres trabalhadoras de um hospital geral.

This article aims to identify factors associated with breastfeeding continuation for at least 12 months among working mothers in a hospital in the south of Brazil. We conducted a cross-sectional study, interviewing 251 women who breastfed after returning to work. Eligibility criteria included non-twin biological children aged between 12 and 36 months and the absence of an illness (mother and/or child) that could affect breastfeeding. The association between breastfeeding continuation and the exposure variables was tested using Poisson multivariate regression. Only one work-related variable showed a significant association with the outcome. Working only during the day increased the prevalence of BF continuation for at least 12 months by 37%. The following non-work-related factors showed a positive association with the outcome: mothers without a college degree; mothers with at least 12 months' prior breastfeeding experience; child not given milks other than breast milk when the mother returned to work, and not using a pacifier. The following variables showed a negative association with the outcome: older maternal age; older gestational age; mother receiving support from the child's caregiver; and mother receiving professional breastfeeding support. Non-work-related factors had a greater influence on breastfeeding continuation for at least 12 months among working mothers.

O objetivo deste estudo é identificar fatores associados à continuidade da amamentação por 12 meses ou mais em mulheres trabalhadoras. Estudo transversal realizado por meio de entrevista com 251 trabalhadoras de um hospital, com filhos biológicos entre 12 e 36 meses de idade, não gemelares e sem doença que afetasse a amamentação, e amamentando quando do seu retorno ao trabalho. Para a associação entre a continuidade da amamentação e as variáveis de exposição utilizou-se a regressão multivariável de Poisson. Apenas uma variável relacionada ao local de trabalho da mulher mostrou associação significativa com o desfecho. Trabalhar durante o dia aumentou em 37% a prevalência da amamentação por 12 meses ou mais. Os fatores não relacionados ao trabalho da mulher que mostraram associação positiva com o desfecho: mãe sem curso superior, experiência de amamentação superior a 12 meses; criança não receber outro leite quando a mãe retornou ao trabalho e não ter usado chupeta. Por outro lado, maior idade da mãe, maior idade gestacional, apoio do cuidador da criança e apoio profissional na amamentação associaram-se negativamente ao desfecho. Fatores não relacionados diretamente ao trabalho materno tiveram maior participação na continuidade da amamentação por 12 meses ou mais.

Psychometric properties of the Child Development Assessment Questionnaire (QAD-PIPAS) for use in population studies involving Brazilian children aged 0-59 months

Abstract Objective: To analyze the psychometric properties of the Child Development Assessment Questionnaire (QAD-PIPAS). Methods: This methodological study was comprised of two axes. The first one aimed to analyze the instrument's construct validity (discriminant and concurrent validity) and internal consistency, and the second one examined test-retest reliability, involving two different samples and procedures. For construct validity and internal consistency, the sample was recruited in Embu das Artes-SP, Brasilia-DF and Recife-PE during the immunization campaign in 2017, involving caregivers of 2005 children under 60 months of age (1295 under 36 and 710 from 37 to 59 months). For the test-retest analysis the sample consisted of 30 children aged 0-59 months old that attended daycare centers in Embu das Artes-SP in 2018. Results: Multivariate analyses of construct validity showed that the QAD-PIPAS was able to identify the association between the outcome (suspected child development delays) and expected risk and protective factors based on Nurturing Care Framework (OMS/UNICEF). A significant positive correlation was achieved between the scores of the QAD-PIPAS and CREDI in six of the eight age groups analyzed, with the most significant correlations being in the age groups from 25 to 30 and 31-36 months. Acceptable internal consistencies were identified in all age groups, with better performance above 36 months of age (Cronbach's alpha between 0.61 to 0.80). We also found an adequate test-retest reliability (global Kappa 0.81). Conclusion: The QAD-PIPAS showed evidence of construct validity and reliability to be used in population studies involving children aged 0-59 months during multi-vaccination campaigns in Brazil.

Factors associated with women's satisfaction with prenatal care in Porto Alegre, Rio Grande do Sul, Brazil. / Fatores associados à satisfação das mulheres com a atenção pré-natal em Porto Alegre, Rio Grande do Sul, Brasil.

This article aims to identify factors associated with full satisfaction with prenatal care in health services in Porto Alegre (RS), Brazil. This is a cross-sectional study with 287 women that attended prenatal care in the state capital. Women were randomly selected at two large maternity hospitals (public and private) and interviewed at their homes around 30 days after delivery, from January to August 2016. Satisfaction was measured by a Likert scale (very satisfied to very unsatisfied). Prevalence ratios (PR) were estimated by Poisson regression with robust variance, using a hierarchical model. Factors associated with greater satisfaction were higher education (PR=1.49; 95% CI: 1.08-2.06); multiprofessional care (PR=1.29; 95% CI: 1.00-1.66); receiving information about breastfeeding (PR=1.33; 95% CI: 1.05-1.68) and place of delivery (PR=1.56; 95% CI: 1.12-2.17); and women feeling comfortable asking questions and participating in decisions (PR=5.17; 95% CI: 1.79-14.96). The findings suggest that prenatal care services that offer multiprofessional care, provide guidance, and make pregnant women feel comfortable asking and deciding about their care may generate greater satisfaction.

O objetivo deste artigo é identificar fatores associados à plena satisfação com a atenção pré-natal em serviços de saúde de Porto Alegre, Rio Grande do Sul. Estudo transversal, com 287 mulheres que realizaram pré-natal na capital gaúcha. As mulheres foram selecionadas aleatoriamente em duas maternidades de grande porte (pública e privada) e entrevistadas nos seus domicílios, cerca de 30 dias após o parto, entre janeiro e agosto de 2016. A satisfação foi aferida por meio de escala Likert (muito satisfeita a muito insatisfeita). Foram estimadas razões de prevalência (RP) por regressão de Poisson com estimação robusta da variância, utilizando modelo hierarquizado. Os fatores associados à plena satisfação foram: ingresso no ensino superior (RP=1,49; IC95%:1,08-2,06); atendimento multiprofissional (RP=1,29; IC95%:1,00-1,66); recebimento de orientações sobre amamentação (RP=1,33; IC95%:1,05-1,68) e sobre local do parto (RP=1,56; IC95%:1,12-2,17); e sentimento da mulher de estar à vontade para fazer perguntas e participar das decisões (RP=5,17; IC95%:1,79-14,96). Os achados sugerem que serviços de pré-natal que oferecem cuidado multiprofissional, que dão orientações, e que oportunizam às gestantes o sentimento de estar à vontade para questionar e decidir sobre seu cuidado, proporcionam maior satisfação.

Risk factors for and protective factors against breastfeeding interruption before 2 years: a birth cohort study.

BACKGROUND: Little is known about the factors associated with the World Health Organization (WHO) recommendation of breastfeeding for at least 2 years. The objective of this study was to identify risk factors for and protective factors against breastfeeding interruption before 2 years of age. METHODS: In this live birth cohort, mother and infant dyads were followed for 2 years. Data collection was performed at the maternity ward and subsequently at the children's homes, monthly during the first 6 months of life and then at 9, 12, 18, and 24 months. The outcome of interest was breastfeeding interruption before 2 years of age. Median duration of breastfeeding was estimated using Kaplan-Meier's survival analysis, and the associations were tested using Cox's hierarchical multivariate model. Significance was set at 5%. RESULTS: Data from a total of 1344 dyads were assessed. Median breastfeeding duration was 385 days. The following risk factors for breastfeeding interruption were identified: white skin color (adjusted hazard ratio [HRa]: 1.31; 95% confidence interval [95%CI]: 1.10-1.56), primiparity (HRa: 1.21; 95%CI: 1.05-1.40), working outside the home (HRa: 1.52; 95%CI: 1.30-1.77), child sex male (HRa: 1.18; 95%CI: 1.03-1.35) and use of a pacifier (HRa: 3.46; 95%CI: 2.98-4.01). Conversely, the following protective factors were identified: lower family income (HRa: 0.81; 95%CI: 0.71-0.94), mother-infant bed-sharing (HRa:0.61, 95%CI: 0.52-0.73), on-demand breastfeeding in the first month (HRa: 0.64; 95%CI: 0.47-0.89) and exclusive breastfeeding at 4 months (HRa: 0.58, 95%CI: 0.48-0.70). CONCLUSIONS: The findings allowed to identify both risk factors for and protective factors against breastfeeding interruption before 2 years of age. Knowledge of these factors may help prevent this event and aid in the development of programs that help women maintain breastfeeding for at least 2 years, as recommended by the WHO.

Psychometric properties of the Child Development Assessment Questionnaire (QAD-PIPAS) for use in population studies involving Brazilian children aged 0-59 months.

OBJECTIVE: To analyze the psychometric properties of the Child Development Assessment Questionnaire (QAD-PIPAS). METHODS: This methodological study was comprised of two axes. The first one aimed to analyze the instrument's construct validity (discriminant and concurrent validity) and internal consistency, and the second one examined test-retest reliability, involving two different samples and procedures. For construct validity and internal consistency, the sample was recruited in Embu das Artes-SP, Brasilia-DF and Recife-PE during the immunization campaign in 2017, involving caregivers of 2005 children under 60 months of age (1295 under 36 and 710 from 37 to 59 months). For the test-retest analysis the sample consisted of 30 children aged 0-59 months old that attended daycare centers in Embu das Artes-SP in 2018. RESULTS: Multivariate analyses of construct validity showed that the QAD-PIPAS was able to identify the association between the outcome (suspected child development delays) and expected risk and protective factors based on Nurturing Care Framework (OMS/UNICEF). A significant positive correlation was achieved between the scores of the QAD-PIPAS and CREDI in six of the eight age groups analyzed, with the most significant correlations being in the age groups from 25 to 30 and 31-36 months. Acceptable internal consistencies were identified in all age groups, with better performance above 36 months of age (Cronbach's alpha between 0.61 to 0.80). We also found an adequate test-retest reliability (global Kappa 0.81). CONCLUSION: The QAD-PIPAS showed evidence of construct validity and reliability to be used in population studies involving children aged 0-59 months during multi-vaccination campaigns in Brazil.

All day-long pacifier use and intelligence quotient in childhood: A birth cohort study.

BACKGROUND: Literature on pacifier use remains controversial, but mostly suggests an inverse association with childhood intelligence. OBJECTIVES: The objective of this study was to assess the association between pacifier use and intelligence quotient (IQ) in six-year-old children from a birth cohort. METHODS: Data from 3532 children from the 2004 Pelotas (Brazil) Birth Cohort were analysed. Children were recruited and assessed at birth and followed up at 3 months, and 1, 2, 4, and 6 years. Data on pacifier use duration and intensity were obtained via interviews with mothers in all six follow-up visits. IQ was estimated at 6 years using the Wechsler Intelligence Scale for Children and standardised for the analyses. Crude and adjusted coefficients were calculated (linear regression) for all the data collected in follow-up assessments for pacifier use. RESULTS: IQ was inversely associated with all pacifier use indicators. Children who used a pacifier all day long (ADL) at any follow-up showed an IQ 0.18 (95% confidence interval [CI] 0.11, 0.24) standard deviations below those who never used it ADL, after adjusting for confounders. The strength of association increased with number of assessments reporting ADL pacifier use, from a reduction in IQ of 0.13 (95% CI 0.06, 0.21) to 0.34 (95% CI 0.15, 0.52) standard deviations for ADL use in one and in all four follow-up visits, respectively. CONCLUSIONS: We found a strong association between intense pacifier use up to 4 years of age and lower IQ at 6 years. A dose-response gradient was observed, with greater IQ deficits in children who used a ADL pacifier for longer durations. The mechanisms underlying this association need to be clarified. One hypothesis is that children using a pacifier, especially those who use it more intensely, are less stimulated.

Effect of a healthy eating intervention in the first months of life on ultraprocessed food consumption at the age of 4-7 years: a randomised clinical trial with adolescent mothers and their infants.

This randomised clinical trial aimed to evaluate the effect of a pro-breast-feeding (BF) and healthy complementary feeding intervention performed during infants' first months of life on ultraprocessed food (UPF) consumption at 4-7 years. We enrolled 323 teenage mothers and their infants from South Brazil, 163 allocated to the intervention group and 160 to the control group. Intervention consisted of sessions on BF and healthy complementary feeding promotion and was carried out in the maternity ward and at home after delivery. Food consumption was assessed using three 24-h food recalls at child's age of 4-7 years. Foods were classified according to NOVA classification. Dietary contribution of UPF was adjusted for intra-individual variability by the SPADE method and categorised into tertiles. We used Poisson regression models with robust variance, adjusted for confounders, to estimate the effect of the intervention and duration of BF on the risk of high consumption of UPF. Our final analysis included 194 children, with mean age of 6·1 (sd 0·5) years. Mean dietary contribution of UPF was 38 % in the intervention group and 42·7 % in the control group, from total daily intakes. Results adjusted for BF duration, propensity score, income and total energy content demonstrated that the intervention reduced the risk of high consumption of UPF by 35 % (relative risk 0·65, 95 % CI 0·43, 0·98). BF duration was not associated with UPF consumption. The intervention was effective in reducing the risk of high UPF consumption at the age of 4-7 years.

Factors associated with a positive childbirth experience in Brazilian women: A cross-sectional study.

BACKGROUND: Having a positive childbirth experience is an increasingly valued outcome. Few studies evaluated the women's satisfaction with childbirth through face-to-face interviews out of the health service environment. The objective of this study was to identify factors associated with a higher level of satisfaction with the childbirth experience among Brazilian women. METHODS: This cross-sectional study involved 287 women giving birth in two hospitals in southern Brazil. Women who gave birth to healthy newborns at term were randomly selected. Face-to-face interviews were conducted 31-37 days after delivery, at the mothers' homes, using a structured questionnaire. Satisfaction with the childbirth experience was measured using a Likert-type scale ranging from very satisfied to very dissatisfied. Prevalence ratios (PR) were estimated using Poisson regression with robust variance. RESULTS: Following hierarchical multivariate analysis, the following factors remained associated with a higher level of satisfaction with the childbirth experience: being satisfied with antenatal care (PR=1.30; 95% confidence interval [95%CI]=1.06-1.59), understanding the information provided by health professionals during labor and delivery (PR=1.40; 95%CI=1.01-1.95), not having reported disrespect and abuse (PR=1.53; 95%CI=1.01-2.31), and having had the baby put to the breast within the first hour of life (PR=1.63; 95%CI=1.26-2.11). No association was observed with type of delivery or hospital status (public or private). CONCLUSIONS: A higher level of satisfaction with the childbirth experience is related to satisfactory antenatal care, a non-abusive, respectful, and informative environment during childbirth, and to the opportunity to breastfeed the baby within the first hour of life. In clinical practice, greater attention to these basic principles of care during pregnancy and delivery could provide more positive experiences during birth.

Development and validation of an instrument for monitoring child development indicators / Elaboração e validação de um instrumento para monitoramento de indicadores do desenvolvimento infantil

Abstract Objective: To create and validate an instrument for child development monitoring. Methods: Methodological study, based on the World Bank's proposition to monitor child development indicators in low- and middle-income countries. The stages of the study included the following: development of an inventory of items for child development evaluation, based on open access instruments; content validation by a group of experts on the topic, using consensus techniques; selection of questions to describe children and their families; pre-test of the instrument during the vaccination campaign in 2016 in three municipalities, and conducting cognitive interviews. Results: A total of 431 items were sent for the evaluation of the specialists; 77 were initially excluded and the others were evaluated in-person by the group, with 162 items covering the motor, cognitive, language, and socio-emotional domains, distributed in ten age ranges. Questions about health, nutrition, early learning, protection and safety, and responsive care were also included. The instrument was applied by volunteer undergraduate students to 367 mothers of children under 5 years, showing good adherence of the caregivers. The time of application of the questionnaire was, on average, 20 minutes. The cognitive interviews allowed the final adjustment of 19 items of the instrument for better understanding by the caregivers. Conclusions: The instrument created and validated by experts fills a gap, as it allows a comprehensive evaluation of the development of children under 5 years at the population level, using a fast and inexpensive tool, and can be useful for monitoring indicators of development in Brazilian children in vaccination campaigns.
